MANGLE To alt whom it nary concern:

Be it known that l. lIUoo A. Hncnnn, a citizen of the United States, residing at. .iellevue, in the county of Campbell. and State of Kentucky, have invented certain new and useful lmprovemei'its in Mangles, of which the following is a specification.

It is the object of my invention to provide new and useful improvements whereby the capacity of mangles may be increased from time to time under retention of the original mangle and the addition of sections of. manglcs from time to time, while providing novel means between nrangle-scetions whereby differences or changes in alinement between adjacent edges of mangle-sections may be compensated for cheaply, readily and con veniently; in providing mangle-sections with flexible 01' resilient conforming bGCl-CODHQC- tions whereby variations between adjacent bed-surfaces of adjoining mangle-sections are readily, conveniently and cheaply overcome; further in new and improved means for guiding the material with relation to the rotating heating cylinder; and the invention will be further readily understood from the followingdescription and claims, and from the drawings, in which latter:

Y Z are mangle-sections, of which I shall designate the section Y the original section, and the section Z the added section, and in my improved device the section Y may form the completed mangle, whether with or Without the steam cylinder hereinafter described, or there may be any desired number of these added sections in the composite completed mangle, and my improved construction is such that sections may be readily added, and the lit between sections readily obtained, from time to time, irrespective of differences in length of time of use between mangleseetions, and this feature is especially valuable as the steam-chests of mangles of this character are liable to and do warp in course of service, and it is essential to have a smooth surface without oti'sets between adjacent mangle-sections forforming abed sur face along which the goods may travclwithout. meeting with obstruction.

The section Y may comprisea frame A c-mtaining heating or steam-chests B O suitably secured therein and having suitable Qsupplv and discharge openings for steam.

.llaugle rolls D F are suitably journalcd with relation to the stcanrchests and tothe tramc. 'Lhc e rolls are. provided with a suit- 'ahlcv compressible covering, and are received adjaccut'to thegconcave surfaces 1 ot' the steam or heating chests. It desired the seetioii Y nay'also be provided with a rotating steam cylinder and cooperating apron therefor in manner hcreatter described.

The rolls-l) F; are suitably supported and driven as by providing each with a shaft. 3 jourm'iletil ina bearing 4: slidable'in guidcway 5 in the respective sides .6 of the frame The hearing has an upwardly extending rod 7 (see Fig. 7) pivoted thereto; said rod having set-nut S at its upper end which hours upon a lever 9 articulated with the frame by means of a link 10. The lever is provided with a pocket 11 in which there is a spring 12 hearing against the roll-bearing for permitting the roll to yield to variations in thickness of stock fed through.the machine. For positioning the rolls with relation to the steam-chests, rods 15 for the re spective levers are provided. Each of these rods has nuts 16 17 respectively above and below the swinging end of the lever and taking against; curved surfaces 18 of the latter, these curved surfaces and the links 10 being 1 provided. for permitting the roll bearings to be adjusted or to yield vertically without cramping the levers. v

The screw rods are held against rotating with relation to the frame by having a squared portion 19 thereon taking against 2: similar opening 20 in the frame, and are v crew-three(led at their lower ends as shown at 21. The screivrods 15 for the rolls of a given mangle-section are preferably adjacent each other and are received respectively into internally threaded worm-gears 22 23 mesh ing with an intermediate worm 24: on a shaft 25, said shaft having a. corresponding Worm.

at each side of the machinethere being corresponding SCFGW-IOtlS and levers for the bearings at each end of the mangle rolls for raising and lowering the bearings of 'both rolls simultaneously depending onthe 'direction ofrotation given the shaft .25 by the hand-Wheel 26.

31 is a drive-shaft jo'urnaled in the frame A and having a gear 32 and 21' pinion 3,3 thereon, the pinion 33 meshing with no inte mediute gear 3 1-01; it stud 35, the. said intermed ate gear meshin with gears 36 37 respectively on the roll-s left of rolls D E for driving the letter.

The added section Z has a frame A containing heating or steam-chests B C. More gle rolls D E with operating devices for the latter similar to those described with reletion to the section Y, are provided, and it is therefore not necessary to particularly enumerate the same, but in the drawings they are indicated by similar reference letters and numerals, but provided with the exgonentprime ezrrings 38 in which a; sheft39 1S journaled, 40 which serves the shaft carrying the etween the driving as u connecting gear gears of rolls'E D". The sides of the frame Aere provided with ineetin faces l2, and the sides of the frame A witi meeting faces 43 42. The frame A is provided with lugs 44, (see Figs. 1 and 8), and the frame A.

with lugs 45 94.4% similar to the lngs i4. Bolts 46 take through the lugs 4.4 45 and ronnect the frames I tnres in said lugs similar to the aperture shown in ll? ed in l i m ts d6" bein re ceiw-z'l o er the threaded ends of the bolts. 'lhe nines are bolted together at both sides oi the machine he manner stated. Addi tionai sections similar to the added section Z mar he provided and add .l in advance of aid 'etion 55. th zidditlonsl sections being construe-ted iilarly' to the added See lion Z. The i'r u'uc tie-rod 47, and the frame A is provided with u tie-rod l Goodsreceptacle F has hoohs 1 taking over the tierod at the feeding-in -enil oi the machine.

It will he understood that in inang'les of this rluiracler the goods travel between the,

strum-Chest and the rolls, and that the greater the number of rolls and steam-chests the .lnrgern ill he thecapucityof'the machine in that the rolls may be driven at greater speedf- In order to insure correct travel of the goods it is essential that the surface upon which the goodstrzivel shall be such that. the goods may not be interrupted or caught. It will be further under stood that the steam-chests are subjected to high and also varying degrees of temperature, and further that these chests are long bodies, sometimes a hundred inches or more v in length, and that in practice. they warp or sag in varyin degrees in course of use, hrii'iging thelongitudinal edges of the steamch'est out of original alinement. The result is that if it is attempted to mate a new section with one'thathas been in use, difierences in alineinent between the two will he found, and if a mangle-section having it new steam-chest- Were'atteinpted to he placed adjacent to a. mangle-section already in use the adjoining steem-chests will be out of longitudinal alinement and prevent proper travel of the goods from one to the other;

or necessitate expensive and tedious fitting away from the shop. To obiriete these ditliculties, 1 provide novel flexible or resilient connection between mangle-sections. (l is a flexible or re ilient plate which I prefer to perforate. l separate the adjacent longitudinal edges 51 52 of the respective steam chests C ll of ad oming mangle-see (lined rubbers '53 l adapted to receive the longitudinzil edges of the resilient plat-e G. l'pr'efer tocurve this plate and to reduce the upper faces of the rsbhets toward their outer ed es for normally forming a. slight space 5:3 lietween the outer edges of the hot lute, so as the inner corner of is rabbet irrespective of the degree to which the plate. must be flexed in order to conform to the shape of the steam-chest. The plate is provided with downwardly projecting rods 58 extending from llan es 57 riveted to the plate. The adjacent longitudinal edges of the stealinchesis are provided with lateral-1y extending lips 4 859, the said longitudinal rabhetsbelug formed in said lips. Clamp-burs 60 take under the lips. The rods 56 take through the clump-bars and have nuts (51 screwing thereon against the chimpdiars for forcing the plaie G into the rizbbet; and causing it to bend and take upon itself the shape towhich. the steam-chest and consequently its 11p and Thus lo the same with longitd,

7 preferably padded, that is,

memes the walls of the rabbet may have been warped in practice, as seen in the exemplificatlon in Fig. ltwill thus be seen that the plate compensates for variations that the shall project into the lateral plane of the succeeding mangle-section, as see the lip 58 of steam-chest C of section Y in Figs. 2 to 5 taking beyond the meeting lines between the sides of the frames of section Y and Z.

If desired .the section A. may be provided with the rotating steam or heating mangle cylinder 65, journaled in bearings 36 in the frame; An endless apron 67 which in practice usually has a width of about the length of the rolls hereinafter mentioned, is adapted to travel about this cylinder for carrying the goods about and pressing said goods against said cylinder for ironing the same. This apron travels about suitable rolls and I have provided novel means for directing the goods with relation to it and the steam cylinder. The apron travels over a roll 68, the upper face of whose periphery is preferably higher than the end lip of the steam-. chest B for receiving and directing the goods from the surface of the steam-chest upon a slightly upwardly inclined stretch 69 of the apron, formed by said belt passing from the roll 68 to a roll 7 O. This roll 70 is covered with felt or canvas or other suitable com ressible covering. The apron' then passes about .the heated cylinder and takes over a. roll 71 which also referably has a compressible covering. T en the apron passes abdut rolls 72, 73, 74, T5 and batik to roll 68. T 1e roll 74 is refer-ably a take-up roll operated in suitab c manner, and the roll 73 is preterably a guide-roll loperatedin suitable manner for guiding the aproii in the proper transverse position upon the steam-cylinder. The rolls 70 71 respectively have journal ends 76 77 journaled in bearings 78 79 in guide-ways 80 81 in the frame. Each of' these bearings is backed by a spring 82 taking into a hollow cap 83 for giving the said rolls resilient pressure toward the heated cylinder, a bolt 8% taking against a washers 85 above the spring for regulating its tension. (See Fig. 12.)

For guiding the goods into contact with and away from the heated c hnder, I have provided novel instrumenta ities. 917 is a curved guide-plate, and may be termed an intake guide whose cylinderedge 92 (see Fig. 10) is nearer the rotary axis of said roll than the outer edge oi? the curved part of said plate. The outer longitudinal end of said plate preferably projects at a tangent from said curved part, as shown at 94. Awidcned mouth 95 between said plate and the apron is thus provided for readily receiving the goods, the intakoguide gradually approaching the apron and roll T0 for directing the goods toward the heated cylinder. After passing betwcen'said plate and apron, the goods pass about the cylinder between the cylinder and apron until they reach the position of the roll 71, be yond which a curved guide-plate 96 is located. the inner or cylinder edge 97 of which is closer to the roll than the outer edge 98 of the same for forming a delivery-chute having an outer widened mouth 99. The cylinder edge 97 rides upon the steam cylinder and is adapted to doll the goods from the (ivlinder, forming a dollar-plate, and the gradually widening space between the (lollc1'- latc and the periphery of the roll prevents crowding or hunching or curling of the goods between the apron and (letter-plate. l have provided novel means for supporting or hanging said guideplates. Thus frame A is provided with an arch 101 upon which I bolt a hangcx bracket 102, there being one of these arches and brackets at each side of the machine. The brackets are provided with slot-s 103-104. Each end of the intake guide-plate 91is provided with a trunnion-piece 105 having va trunnion 106, and each end of the'dolierplate is provided with a trnnnionpiece 107 having a trunnion 109. These trunnionpiecos have curved faces to correspond with the curving of the guide-platos, which latter are riveted thcrcto.

Hangers 109 110 are secured to the extensions l02,-as by having bolts 111 ll! take through apertures in said hangers and said slots 103 10% respectively. haid hangers are providedwithtrunnion-boarings 113 114 which are preferably open at the top so that the respcctivc gnidc-platcs may be read. ily slipped into position by having their trunnions droppcd into the trunnion-Man ings of said hangers-1. in normal position the cylinder edges of said rcspcctive plates bear against the steam cylinder by gravity purposes and bring the feeding-in and feedperiphery of the heated cylinder for ironing I ing-ont rolls, with their respective guide For driving the shaft ill of section Y and I inoned plates between said rolls said trunihe steam eylinder. i provide an initial drive-shall 117. whieh'may be driven 'lrom a pnllev li(' The shall 115 has a pinion ll? seenred thereto. \vliiel latter meshes 3 with a gear 118 on ahal't 110 having a pingear indieated at 125 on the steam e vlinder shalt.
